    Of course we're doing it all over again.

    The problem is not models. The problem is people totally unable to accept temporary setbacks. If we just let the banks go under last year, the crisis would have been just about over today. Thanks to Bush's caving to wall street which prolonged the crisis a little bit, and now infinitely multiplied by obama's demagogic "let's save everybody" attitude, we are going to get clobbered financially for at least 2 years, more probably 10 years.

    Actually the assumption is this. "Lousy" mortgages are mortgages with 12% chance of default (and this was extremely high, most were something like 2% or so).

    So let's calculate what happens :
    1000 "lousy" mortgages, $200000/house, profit if fully paid back = $20000, over 20 years, profit in case of default = value of house (which rose about 1% per year on average). Default occurs "on average" after 1 year.

    So let's see :

    Initial investment : 1000 * -$200000 = -200000000
    Income from defaults : 120 * ( $200000 + 1% * $200000) = $24240000
    Income from success : 880 * ( $200000 + $20000 ) = $24240000

    Total profit : $24240000

    I dare you to find the flaw in these numbers. Yet there was a flaw. Without an education in statistics you will not see this coming, and even if you do, it's not trivial at all :

    That 12% failure rate was non-uniformly distributed. So what happened ? First 10 to 15 years nobody defaulted, resulting in a house price hike that was a lot higher than anticipated (and therefore further increasing the profits and decreasing the risk to the banks), and then, after 16 years of tiny amounts of failure, huge amounts of people started defaulting all at once, causing a massive decrease in house prices.

    This is where the theory of "let's just support the banks for one year and they'll pull through" theory comes from. IF default rates drop massively it will work.

    So why did this break the banks ? Well due to hedge funds. Hedge funds are the equivalent of using borrowed money in a casino. If you win, it multiplies your winnings. If you lose, it multiplies your losses. When a small loss accumulated, it was massively multiplied (as in a factor of 1000 was not rare) by hedge fund managers. Whether the "smaller" original loss would have been enough to topple banks, we'll never know. One thing is for certain, all these "oh I predicted it" hedge fund managers are like the devil laughing at his victims burning ... they're not innocent of the crash, at all. They're the maffia bosses who massively profit by making loans they KNEW the debtors wouldn't be able to repay.

    And now they act all "I told you so".

    After all, as long as house prices keep rising, there is NO risk whatsoever in dodgy mortgages. Either you get the stated intrest (buyer pays mortgage) or you get the price rise of the house since the buyer bought it with your money (in the case of default) ... the risk of losing money in the deal is EXACTLY the chance that house prices drop.

    From the wikipedia page :

    Tellurium is extremely rare, one of the nine rarest metallic elements on Earth. It is in the same chemical family as oxygen, sulfur, selenium, and polonium (the chalcogens).
